Abstract

A roller mounting for a sliding panel, especially for cladding around a machine, has a single support rail with several tracks; one central track for horizontal axis rollers and upper and lower tracks for vertical axes rollers. The rollers are simple radial support rollers. The support rail is fitted to a fixed mounting near the bottom edge of the sliding panel and is gripped by two or more roller sets.

Description

The The invention relates to a trim arrangement, in particular a Machine panel, with at least one sliding door and one Roller guide assembly.

Sliding doors are typically hung on the top edge in a guide rail and can additionally led the lower edge in another rail and / or on rollers supported on the ground be.

at Machine panels with sliding doors are often the panel around the Work area of a work table arranged, with the work area is open at the top and therefore no Einhängemöglichkeit a sliding door at the Upper edge is made, and the sliding door is not up to the ground enough and a support deleted by floor rolls. In a developed by the applicant and z. B. in a leaflet "Bader Machine panels "from November 2003 is machine paneling with sliding doors a roller guide assembly with a machine-side rail arrangement and a door-side Carriage arrangement provided, in which the rail arrangement a against the height the sliding door low altitude having. The depth of the rail assembly is again essential lower. The carriage assembly on the side of the sliding door is in whose lower area is located at the lower edge of the sliding door. In an upper portion of the rail assembly is a downwardly open guide rail and deeper within the rail assembly another to the side open guide rail on a common carrier rail attached. The guideways the guide rails have a convex arch Cross-section in which rollers are guided with correspondingly curved treads. The Rol lenführungsanordnung takes advantageously very little space on the machine to complete and begins both the weight of the sliding door as also their tilting moment about the direction from. About eccentric adjustable roles in the respective role groups can be a leadership game minimized or even a slight preload of the roller group in the guide rails be set. When overlapping The double doors, which are movable relative to each other, can be further from the Rail arrangement spaced door by means of under the other door thorough Mounts be hung in the rail assembly. The carriage arrangements are then divided into two sub-cars.

Of the The present invention is based on the object, a further improved Such a fairing arrangement with a sliding door as well one in particular for this suitable roller guide arrangement specify.

Inventive solutions are in the independent ones claims described. The dependent ones claims contain advantageous embodiments and developments of the invention.

The Equipment of the roller group with vertical axes, below also named second role group or second group of roles, with two subgroups, each with several roles increases the Number of rolls used and requires one more guideway in the rail arrangement and thus seems more complex at first glance, but surprisingly brings a number of significant advantages over the known arrangement.

By the only radial support the roles of the two subgroups in the upper and lower guideway can both the roles and the Füh rungsbahnen much easier and cheaper accomplished be. The roles can as a low-cost, stable and easy-running support rollers with only radial load of the roller bearing and preferably circular cylindrical Roller tread are running, whereas in the known arrangement radially and axially loaded guide rollers with on the guide rails specially tuned multi-faceted or are used in cross-section convex treads. The upper and lower guideway can advantageously to each other and to the role axes of the subgroups parallel flat surfaces as running tracks and can easy and inexpensive be made by forming a sheet. According to one particularly advantageous embodiment are upper and lower guideway one piece in a rail, in particular one of a flat sheet metal by bending, in particular folding, produced sheet metal rail educated. The profile rail can in particular the shape of a to the sliding door or have the open at this carriage assembly C open.

Due to the only radial support of the roles of the two subgroups in the respective raceways take these roles only horizontal forces. The vertical forces, in particular the weight of the sliding door are to be intercepted by other elements of the roller guide, which preferably by the roller group with horizontal roller axes, hereinafter also referred to as the first roller group or first group of rollers, takes place. Conveniently, these rollers of the first roller group can be supported only radially on an associated track, since horizontal forces of a tilting moment are reliably intercepted by a travel direction or longitudinal direction of the rail assembly by the vertically spaced subgroups of the second roller group. The first roller group can therefore also advantageously support rollers contain only radial bearing load and preferably circular cylindrical roller bearing surface and assigned to a flat surface as a career.

According to one preferred embodiment then are the roles in the first role group for recording vertical and in the subgroups of the second role group for recording horizontal Force components in each case only radial support on the associated raceways accomplished and inserted and the raceways each as parallel to the roller axes surfaces executed. The roller guide arrangement can also be a total tilt angle, which advantageously less than 30 ° in particular is less than 15 °, be mounted inclined. Typical and below as standard case however, the mounting orientation with vertically oriented is assumed Role axes of the second role group.

The guideway with the horizontal track for the first role group is in an advantageous embodiment designed as a separate rail and at one for the upper and lower guideway the two subgroups of the second roller group common guide rail attached. The guideway for the first roller group can advantageously as the sliding door open U-profile accomplished be. The career for the first group of roles can also be slightly downwards, to the slipping possibly on the career falling chips or favoring other particles. The Roller axes of the first rollers are then advantageously also the same inclined and parallel to the track. The angle of inclination of such possibly given inclination of the track for the first roller group advantageously less than 30 °, in particular less than 15 °.

The by the only radial support the rollers in the guideways advantageously flat design The raceways conveniently tolerates one to a limited extent variable positioning of the rollers in the guideways in the direction of the roller axes. This is for example an advantage in terms of the composition of the rail assembly of several separate guideways for the different role groups, in particular a common guide rail with upper and lower guideway for the Subgroups of the second role group and an additional, on the common guide rail fastened first guide rail with a career for the first role group. Slight deviations of the relative positions from common guide rail and first guide rail impair the function of the arrangement is not. The same applies to tolerance deviations the relative positioning of different role groups in the carriage assembly to each other and / or to the rail assembly. The position-tolerant position of the roles of the different role groups in the assigned guideways is also beneficial in terms of possibly given different thermal expansion individual components of the roller guide arrangement. A relative Displacement of roller groups in the guideways due to thermal expansion impaired the function, in particular the smoothness and precision of the Roller guide assembly Not.

advantageously, contains the second group of rollers at least three in the direction of travel against each other offset roles, of which at least one roll transversely to the direction of travel and is adjustable transversely to the roller axis to a small extent. This can z. B. over an eccentric to the roller axis running portion of a bearing pin be realized, which with the eccentric section in one Hole of the carriage assembly is fitted. Such adjustable Rolls are inexpensive available. When dividing the carriage assembly in two sub-cars, which in the direction of travel are spaced, are advantageously on each sub-car subgroups of first role group and the upper and lower subgroup of the second Role group available. Each of the two subgroups of the subgroups the second role group, that is the role group with the vertical ones Roller axes, contains while advantageously at least two individual roles, of which preferably in each case at least one roller transversely to the direction of travel and to the roller axis is adjustable.

The Division of the carriage assembly in two spaced in the direction of travel Subcar is in itself from the machine covers mentioned above known and enabled by the applicant especially the overlapping Movement of two sliding doors in the same rail arrangement. The part cars of the carriage arrangement are advantageously at least 50%, in particular at least 75% of the width of the sliding door spaced from each other in the direction of travel and preferably to opposite set edges the sliding door arranged. Preferably, the outermost in the travel direction Roles of the individual role groups, subgroups or subgroups arranged close to the spaced in the direction of travel side edges of the sliding door.

In a first advantageous embodiment, the first roller group can consist of only two rollers spaced apart in the direction of travel, which rollers are then arranged marginally preferably far apart from each other, in particular with regard to the door width of the sliding door. The first track of the rail assembly for the first roller group can be performed in a simple embodiment only as a single track below the rollers of the first roller group and support the first roller group vertically. In a preferred embodiment, the first guideway two vertically spaced guideways, between which the first roller group is guided, so that a lifting of the first roller group is limited or prevented by the first guide track upwards. The first roller group can then also contain at least three rollers, of which preferably at least one transverse to the direction of travel and transversely to the roller axis is adjustable. When dividing the carriage assembly into two spaced sub-cars, each subgroup assigned subgroup pe the first roller group only one role, in a preferred embodiment depending at least, in particular exactly two roles, one of which is adjustable, in a first simple embodiment. Instead of the guideway with two the first roller group between them enclosing raceways of the first guideway may also be provided a guideway in which a web strip facing away from one another at an upper side and at its bottom a lower track and the first roller group with vertical offset rollers above and below the web strip.

In another advantageous embodiment a career for Rolls of the first, group, on which these roles the weight the door arrangement vertically supported is, in one piece with at least one, preferably two guideways for the rollers the second group be. In particular, a career for roles of the first group two raceways for Connect roles of a subgroup of the second group. In preferred embodiment For example, the rail assembly may be formed from a one-piece rail of C-shaped cross-section consist.

The Rail arrangement is advantageously on the machine table or preferably a machine frame carrying this to be clad Machine attached. The mounting height the rail arrangement is advantageously chosen so that the upper edge of the rail arrangement below the table level of Machine table is located, so that access to the partial area at open sliding door through the rail assembly is not obstructed. The height distance of the upper edge of the rail arrangement against the height the table level is preferably less than the height of the rail arrangement between its upper edge and lower edge. The height of the rail assembly is typically small against the height the sliding door and is preferably less than 30%, in particular less than 20% of Door height. The Rail arrangement and the door side Cart assemblies are advantageously in a lower area the sliding door, in particular arranged on or close to the lower edge. Of the Focus of the sliding door is located typically higher as the carriage assembly The sliding door is against its weight and tilting moments at least during the passage along the rail arrangement only over the roller guide supported and especially not in addition held or guided in the region of its upper edge.

In another variant of the invention may be a roller guide on a machine panel Have roles with substantially horizontal roller axes, which non-cylindrical treads have and are guided in non-planar raceways of a guide assembly and designed both radially and axially with respect to the roller axes supporting and are arranged. The roles are advantageously two vertically spaced subgroups each with its own of at least two vertically spaced guideways assigned. Such an arrangement allows a fairing arrangement with a particularly low horizontal construction depth across the travel direction.

The on the preferably metallic running surfaces of the roller conveyors in the Rail arrangement rolling rolling surfaces of the individual rollers can advantageously made of metal or in particular also of plastic, wherein Plastic bearing surfaces also by attachable and / or interchangeable caps on metallic Rolls can be formed.

The 1 shows in oblique perspective view from the machine side a sliding door ST with a roller-loaded carriage assembly WA and a rail assembly SA. For assistance with the further explanations, a rectangular xyz coordinate system is shown. The sliding door ST may include a glazed viewing window FE. The door height HT in the z-direction and the door width BT in the x-direction can vary over a wide range. Typical dimensions are in ranges between 0.5 m and 2.5 m. The ratio of door height to door width can also vary over a wide range. The carriage assembly WA is in a lower region, in particular a lower third, preferably a lower quarter of the sliding door ST attached thereto. In the example outlined, a carriage arrangement which is continuous in the x-direction is provided, whose width BW is approximately equal to the door width BT. The height HW of the carriage assembly is small against the door height and is typically less than 30%, in particular less than 20% of the door height HT. The structure of the carriage assembly in detail is based on the 3 still described in detail. The rail assembly SA is shown partially cut away to show a first guide rail S1, which is otherwise concealed in this view by a second guide rail S2. The width BS of the rail arrangement of the SA is advantageously at least approximately twice as large as the width BT of the sliding door ST, but may also be greater. The height HS of the rail assembly SA in the z-direction is approximately equal to the height HW of the carriage assembly WA. The depth TS of the rail arrangement is low and is advantageously less than 50 mm. The depth TS of the rail assembly is substantially less than the height HS of the rail assembly. The height HS is advantageously at least 3 times the depth TS. The rail assembly SA is connected to the in 1 visible back attached to a machine table or machine frame, preferably bolted. The first rail S1 and the second rail S2 are connected in a defined relative position, preferably welded together.

In 2 is outlined a situation with inserted into the rail assembly carriage assembly and on the roller guide formed by rail assembly and carriage assembly in the longitudinal direction x movable sliding door ST. In 2 In addition outlines of a machine panel with lining sections MV1, MV2 are sketched, between which a door opening VO is free. The sliding door ST can be moved along the rail assembly in the x-direction between a closed position in which it covers the door opening VO and an open position in which it lies substantially completely in front of the covering section MV1 on its user facing side. The sliding door is in 2 sketched in an intermediate position. Weight forces of the door and tilting moments of the door from its weight or other loads in operation around all coordinate axes are absorbed exclusively by the roller guide with the guided in the rail assembly carriage assembly.

In 3 is in various views ((A) oblique view, (B), (C), (D) looking in the x and y or z direction) a preferred embodiment of a carriage assembly WA for a trim arrangement according to 1 . 2 outlined. The carriage arrangement has a carrier body TK which extends in the longitudinal direction in an integral manner and in the form of a profile rail, as well as a plurality of support rollers. The support rollers are subsequently divided into a first roller group R1 and a second roller group R2, which in turn is subdivided into an upper subgroup RU2 and a lower subgroup RU2. The rollers R11, R12 and R13 of the first roller group R1 are fastened to a vertical surface F1 of the carrier body TK with roller axes pointing horizontally, ie in the y direction. In at least one of the rollers, the roller axis is eccentric against a roller position determining hole in the surface F1 and the position of the roller axis is in such an adjustable role in the z-direction, ie transversely to the roller axis and transversely to the direction x to a limited extent adjustable. The roller axis of the middle roller R12 is offset relative to the roller axes of the rollers R11 and R13 by a small amount AV1 in the z-direction upwards. The outer rollers R11, R13 of the first roller group are positioned far apart in the x-direction and are preferably fastened to the opposite ends of the carrier body TK on the latter. The roller R12 is advantageously arranged approximately in the middle of the carrier body in the x-direction. The rollers RO21, RO22, RO23 and RO24 of the upper subgroup RO2 of the second roller group are fixed to a horizontal upper surface FO2 of the carrier body with substantially vertically oriented roller axes. Preferably, in turn, the rollers RO21 and RO24 which are external in the x-direction are spaced apart from one another and in particular are fastened close to the opposite edges of the carrier body or its surface FO2. Notwithstanding the division of the first group of roles are in the example shown, the upper subgroup RO2 of the second group of rollers between the outer rollers RO21 and RO24 two more Rollers RO22 and RO23 are provided, which are arranged close to the outer rollers and in turn against these show a slight horizontal axis offset AV2 in the y direction. The paired roles may, in anticipation of an example to be described later in detail, be regarded as subgroups within the subgroup RO2. Advantageously, it can again be provided that in each subgroup at least one of the rollers is adjustable transversely to the direction of travel and transversely to the roller axis, ie in this case in the y direction, by a small amount. A lower subgroup RU2 of the second role group is constructed analogously to the upper subgroup RO2, so that reference is made to the explanations made to the subgroup RO2. While the rollers of the upper subgroup facing away from the mounting surface FO2, the rollers RU21, RU22, RU23 and RU24 from a horizontal lower mounting surface FU2 of the carrier body TK down. It is also possible to provide more subgroups than sketched and / or more individual roles per subgroup. The sketched division is particularly advantageous.

Of the Carrier TK also has an upper vertical support surface FBO and a lower vertical holding surface FBU on, over which the carrier body directly or over Attached intermediate elements on the side facing away from the user of the sliding door can be. Due to the vertical spacing of the two retaining surfaces there is a stable connection between the carrier body and the sliding door, which in particular also for absorbing tilting moments about the x-axis is advantageous. The mounting surface F1 for the rollers of the first roller group is against the holding surfaces FBO, FBU in x-direction away from the user and to the track layout SA offset, which on the one hand on the sliding door facing Side of the mounting surface F1 place is for the fixing screws on the threaded bolts of the support rollers and second, the rollers themselves closer to the vertical back wall of the Move rail arrangement, what for support the weight of the door in a guideway for the first roller group R1 is advantageous.

If no relevant tilting moments the sliding door parallel to the y-direction Axis can be expected, the middle role R12 of the first role group also omitted or replaced by a simple stop element be. In another version can also in the first group of roles in the x-direction spaced subgroups each with at least two roles analogous to the described structure be provided the upper and lower subgroup. The subgroups can also have more than two, especially three single roles.

In 4 is a preferred embodiment of a rail assembly with an inserted carriage assembly of the in 3 sketched type with viewing direction shown in the x direction. The rail assembly includes a first track for the rollers of the first roller group R1, an upper second track for the rollers of the upper subgroup RO2, and a lower second track for the rollers of the lower subgroup RU2. The upper second guideway is formed by a U-shaped, downwardly open profile section whose connected via an upper center section OF vertical profile leg at the mutually facing inner profile surfaces form a front track LO2V and a rear track, wherein by the axial offset AV2 of the longitudinal direction spaced individual roles of the upper subgroup some roles, eg. B. RO21 and RO24, are supported on the front race LO2V and other roles with offset in the y-direction roller axes on the rear track LO2H. Between the axle of the rollers and the upper connecting central portion OF there is a small distance, which on the one hand manufacturing tolerances and on the other small vertical displacements between the subgroup RO2 and the upper second guideway, z. B. by different thermal expansion of rail assembly and carriage assembly permits.

In appropriate way can for the roles of the lower subgroup RU2 a lower second guideway provided in the form of an upwardly open U-shaped profile section be at whose over one Middle section OF connected vertical profile legs a front Track LU2V and a rear track LU2H are formed. The clearance between the axle bolts of the rollers of subgroup RU2 and the middle section OF here still has the special effect that in the lower profile section incident smaller particles, in particular chips a material processing operation, the movement of the carriage assembly do not interfere. The middle section OF can for This effect may also be lower than in the sketch and / or can Breakthrough che have, by which such particles precipitate down again can.

The lower and / or the upper profile section can be formed in a preferred embodiment by forming, in particular rolling or folding a sheet metal section. The upper and the lower profile section are advantageously connected to one another via a vertical rear surface RF and are preferably designed as a one-piece C-rail open towards the carriage arrangement. The rear surface can, in particular in the form of openings for the implementation of fasteners, such. B. screws to fix the rail S2 to be prepared on a machine frame. The back surface RF is in the sketched Favor example just executed.

A first guide track for the rollers of the first roller group R1 is in the example of the rail arrangement according to 4 formed by a first rail S1 in the form of an open towards the carriage assembly U-profile, the inner profile surfaces form a lower track L1U and an upper track L1O on the horizontal profile legs. The central portion connecting the two profile legs is advantageously used for attachment, preferably welding, of the first rail to the side of the rear surface RF of the second rail S2 facing the carriage arrangement.

The rollers of the first roller group essentially support the weight of the sliding door on the lower track L1U. If there are more than two roles in the first role group, as in the example below 3 roll off advantageously at least two rollers on the lower track L1U, these rollers are advantageously far apart in the longitudinal direction x, such as. B. the roles R11 and R13 after 3 , The vertical play of these two roles within the first guideway can in unfavorable situations to a niedri conditions, limited by conditioning one of the two rollers on the upper track L1O and / or by investing bearing pin of rollers of the upper part of the central portion OF tilting movement of the sliding door lead around a tilting axis parallel to the y-axis. Such a tilting movement can be prevented from the outset by at least one other role, such. Example, the role R12 in the example 3 , Which has an axial offset AV1 vertically against the rolling on the lower track L1U roles and, where appropriate, even with slight bias voltage applied to the upper track L10 and can roll. If such a tilting movement about a tilting axis parallel to the y-axis is not to be expected or is not considered serious due to the small tilting clearance, only a lower running track L1U may be provided in the first guide track. The rollers of the first roller group are variably positionable within the first guide track parallel to their roller axes, which again advantageously permits positional tolerances between the positions of the first rail S1 on the track arrangement and the first roller group on the carriage arrangement and / or positional changes due to thermal expansion. The lower track L1U may also be slightly inclined to the carriage assembly down in another, not sketched design to counteract the deposition of particles on this track. Advantageously, then the roller axes at the same angle, which is preferably against the horizontal (y-direction) is less than 30 °, in particular less than 15 °, inclined and again parallel to the lower track. The upper raceway L10 is then also inclined and parallel to the lower raceway.

The first guideway is advantageously located vertically between the upper and the lower guideway and preferably in the y-direction between the front and rear Runways of the upper and lower tracks. The roles of the upper and lower subgroups of the second roller assembly wei sen advantageously a small diameter to the depth of the rail assembly to keep low. In contrast, the roles of the first group of roles can be a larger diameter exhibit.

For training the guideways and corresponding arrangement of the roles of the different role groups, in particular the first roller group are different from those described above execution different variants conceivable, which have the advantage of only radial Loading the rollers in the guideways and thus the choice of long-lasting, smooth-running and cost-effective support rollers maintained.

In 5 (A) For example, one of only a flat sheet, z. B. produced by rolling and / or folding rail assembly shown, in which the upper and lower guideways for the roles of the upper and lower subgroup, as in 4 are designed as downwardly or upwardly open U-shaped profile sections. The rear surface RFS forms in the form of an upper loop OS and a lower loop US two projections in the direction of the carriage assembly or the sliding door. The two projections form with mutually facing, vertically spaced tracks L1O and L1U a track for the first roller group with the function of the first rail S1 after 4 , It is here advantageous to reshape only a small sheet metal part.

• – durch die nach unten weisende Fläche OFL des oberen Mittelabschnitts OF gebildet sein, wofür wenigstens eine Rolle der ersten Rollengruppe vertikal nach oben und in x-Richtung gegen die Rollen der oberen Teilgruppe RO2 versetzt angeordnet wird.,
• – durch die nach unten weisende Fläche USL des unteren Abschnitts US gebildet sein, wofür wenigstens eine Rolle der ersten Rollengruppe vertikal nach unten versetzt unterhalb des Vorsprungs US angeordnet ist,
• – durch die nach unten weisende Fläche UFL des unteren Mittelabschnitts OF gebildet sein, wofür wenigstens eine Rolle der ersten Rollengruppe unterhalb der Unterkante der ersten Schiene angeordnet ist.

In 5 (B) is a modified form too 5 (A) sketched in which only a lower projection US is formed from the rear surface to the sliding door, which with its overhead section a lower track L1U for the first roller group corresponding further career required or desired to even small tilting movements about one to the y-axis Prevent parallel tilt axis, such a further career z. B.

• - Be formed by the downwardly facing surface OFL of the upper middle portion OF, for which at least one roll of the first roller group is arranged vertically upwards and in the x direction against the rollers of the upper subgroup RO2.,
• - Be formed by the downwardly facing surface USL of the lower portion US, for which verti least one role of the first group of rollers verti kal is offset down below the US projection,
• Be formed by the downwardly facing surface UFL of the lower central portion OF, for which at least one roller of the first roller group is arranged below the lower edge of the first rail.

Also for the the weight of the sliding door a career of the first guideway supporting, at least two roles R11, R13 of the first role group can be different be arranged and z. B. on the upwardly facing surface OFO of upper center section OF or at the upwardly facing surface OFO support the lower center section OF, so that u. U. on one separate structure, such as the tabs OS, US or the first rail S1 for the first guideway can be waived.

In 6 is a carriage assembly outlined in the lower part of a sliding door, in which two spaced in the travel direction x, in particular maximally spaced sub-cars TW1, TW2 are provided which each contain subgroups of the first roller group and subgroups of the second roller group. Each subgroup UGOR, UGOL, UGUR, UGUL of the subgroups of the second reel group advantageously contains at least two, preferably exactly two individual reels, of which advantageously at least one single reel in the y direction is adjustable in each case. The distribution of the rollers of the second roller groups is in the carriage assembly after 6 essentially the same as in the carriage assembly 3 , Wherein, however, in the direction of travel continuous profile is not provided as a carrier body, but two spaced sub-cars TW1, TW2. The separation of the carriage assembly into two sub-cars is particularly advantageous for the overlapping in the x-direction Verfahrung two offset in the y-direction against each other sliding doors with offset in the traversing and interlocking carriage assemblies with two separate sub-cars in the same rail arrangement. For the sliding door facing the user, sub-carriages are in particular formed with a carrier engaging under the lower edge of the sliding door facing away from the user. The division of the carriage assembly in two sub-cars is known per se from the aforementioned prior art.

The Subgroups UG1R, UG1L of the first role group with the essentially horizontal roller axles each contain at least one roller. A second role in each of these subgroups may be with misalignment AV1 in z-direction be provided to a tilting movement in the manner described the door to prevent.

In 7 is outlined in an oblique view of a preferred embodiment of a parts car, in which a carrier body TT, which advantageously consists of one piece of an angled sheet metal, which the carrier body TK after 3 having corresponding surface portions for attachment of rollers and for fastening the part of the car on the sliding door. In addition to the particularly advantageous, multi-folded profile shape as well 3 described in detail can advantageously be provided in the angles between the upper and lower mounting surfaces for the rollers and the vertical support surfaces for loading fastening of the van on the door still bent tabs BL, which z. B. can serve to stiffen the profile and / or attachment of bumpers AP. 8th shows a sectional view by a roller guide with a part car after 7 in a rail arrangement as in 4 , The in 7 and 8th Sketched sub-car is particularly advantageous due to the easy to manufacture and compact design.

9 shows a carrier body for roles of a sub-carriage accordingly 7 in another version. Significant difference from the execution after 7 is that the raceways for the rollers of the first group are not in a vertical section between the raceways of the vertically spaced subgroups of the second group of rollers, but with these at approximately the same height.

The carrier body after 9 is drawn in the oblique view for the sake of clarity without the roles. The roles and their orientation result from the marked bearing bores L1O, L1U, L2O and L2U. The support body is advantageously produced from a flat sheet metal blank by multiple folding. In particular, the individual surface sections are formed with the bearing bores for receiving the roller axes in extension surfaces of a wall plate VW. The wall panel VW has in the installed state of the sliding door and is advantageously mounted on a vertical wall surface of the sliding door. In side surfaces with parallel to the x-direction surface normal again openings LP are provided for attachment of stop buffer elements.

In 10 is a part car with a carrier behind 9 including the rollers mounted thereon in a state inserted in a rail arrangement in a viewing direction y on the wall surface VW (view A) and in two views in the x direction as stepped partial sections at the height of rollers RHO, RHU with vertical roller axis ( 10 (B) ) or rollers RVO, RVU with horizontal roller axis ( 10 (C) ).

The rail assembly consists in this preferred embodiment only of a one-piece rail with in cross-section after 10 (B) respectively. 10 (C) C-shaped profile. The rail SC thus corresponds substantially to the rail S2 after 4 , wherein in the embodiment according to 9 and 10 no additional rail is provided as a guide track for vertically supported rollers of the first roller group.

The rollers RHO, RHU of the second roller group with vertical roller axes correspond in function and in a vertical arrangement largely to the rollers RO2 and RU2 of the second roller arrangement 4 , In the example shown, the second role group with the vertical role axes in a lower role group contains only one role RHU and in an upper role group two roles RHO. The leadership of the roles of the subgroups of the second roller group with the vertical roller axes can be carried out again substantially as in the embodiments already described. In particular, on the one hand surfaces of the rear wall CR of the rail SC form an upper rear career COR and a lower rear career CUR and this in the y direction horizontally spaced opposite inner surfaces of vertically angled legs of the C-profile form a front upper career COF or a front lower track CUF.

at the upper subgroup with rolls RHO can be provided again, that one of the rollers in the y-direction is adjustable to one of Roll RHO at the rear run COR and another one of the rollers RHO to rest on the front track COF. The two Roll RHO can but also in the x-direction aligned or in y-direction by the same Measures of the wall surface VW spaced positions of their roller axes may be arranged. A small game of roles between the opposing careers in of the order of magnitude fractions of a millimeter can be deliberately accepted. Also for the lower role RHU of the lower subgroup of the second role group If no other specific measures are foreseen, this will be the case such little play of millimeter fractions in the y direction.

The front and rear raceways COR, CUR or COF or CUF for the upper and lower rollers of the second roller group are connected by horizontal profile legs OF and OF with the rear wall CR of the rail SC. These vertical profile legs are used in the execution 9 and 10 advantageously at the same time with their inner surfaces as lower roller bearing CU for the lower rollers RVU the first roller group or as upper race CO for the upper rollers RVO the first roller group. The weight of the sliding door connected to at least two sub-carriages is supported exclusively by the lower rollers RVU of the first roller arrangement on the track CU of the lower profile limb OF. The upper rollers RVO of the first roller assembly serve primarily to prevent tilting of the door about an axis parallel to the y-axis. The upper rollers RVO are therefore typically only exceptionally when moving the sliding door on the upper tread CO on. The upper rollers RVO can therefore be replaced by a simpler Kippbegrenzung, for example, continued from the wall surface VW tab or, if no tilting moment is expected to a tilt axis parallel to the y-direction, also completely eliminated. In another embodiment, the vertically spaced rollers RVU, RVO the first roller group can also be guided slightly biased to vertically play-free guidance in the rail SC, in particular, the upper roller RVO this role group carrying tab can be designed resiliently. Even with the rollers of the second roller group, individual rollers can be mounted with limited elastic resilience and rest under elastic bias on the treads.

The remarks on modifications of the concrete examples given to the preceding exemplary embodiments are also based on the example, in particular with regard to the roles of the first group and of the continuous or two-carriage subdivisions 9 and 10 transferable. Rolls of the first group may also run on the outer upper surface of the upper horizontal profile leg OF and be vertically supported.

In 11 is a roller guide assembly with a particularly low overall depth in the y direction in two versions (A) and (B) outlined. A typical feature of these roller guides is that the rollers used are supported both radially and axially in the roller bearings and likewise guided radially and axially with respect to the roller axes in guide tracks. Example of 11 (A) RV rollers are used whose non-planar roller treads have from the axial edges forth in cross section to the center of the roller treads tapering toward each other, inclined against the roller axis inclined roller treads. The roller guides in a rail SV, which is advantageously made as a profile rail by folding or rolling or other deformation of a flat sheet, the roller treads adapted trajectories are provided in the y- and z-direction inclined orientation. The rollers RX, the roller axes are mounted on a support plate VT, are guided with their roller treads FV both radially and axially in a defined position in the rail SV. Again, upper and lower subgroups of roles are anticipated hen, which are guided in corresponding vertically spaced own guideways of the rail SV.

In 11 (B) an embodiment is sketched in which rollers of an upper subgroup have a different non-cylindrical shape of the roller surface FK with a recess of the roller tread towards the axial center of the roller. In this recess of the roller rolling surfaces FK of the rollers RK of the upper subgroup engages a downwardly angled extension of the rail SK as a guide LK. The rollers RK of the upper subgroup are axially loaded substantially with respect to their roller axes in order to prevent tilting of a sliding door assembly about a direction parallel to the direction of tilting axis. A radial loading of these rollers occurs, if they do not rest with elastic bias on the upper track, only exceptionally at a tilt load of the sliding door assembly in the x-direction.

12 shows a further advantageous form of a roller guide assembly with a guide rail, which on both sides against the vertical inclined tracks FGO. FZO in an upper management area ( 12a ) and FGU, FZU in a lower management area ( 12b ) having. The roller axes of the first and second rollers in the upper and lower guide areas are also inclined to the vertical and substantially parallel to the raceways, so that the rollers are in turn only loaded radially. The inclination angle of the raceways and roller axes against the vertical or generally against the rear surface RS of the C-shaped guide rail SCK is advantageously between 30 ° and 60 °, preferably at ± 45 °. The inclination angles of different raceways may deviate from the sketch 12 be different.

In 12 an upper raceway guide area of the guide rail SCK is shown with a front inclined track FGO for a first upper roller RZO with roller axis parallel to FGO and with a track FZO for a not drawn second upper roller with parallel to FZO roller axis.

In a corresponding manner, the guide rail SCK follows in a lower guide region 12b a front inclined track FGU for a not shown first lower roller and a track FZU for a second lower roller RGU.

The Angle WO above or WU below between the differently inclined Running tracks do not serve as running surfaces and can therefore be additional Have structures or used to attach other components become. For example, you can In the lower angle recesses AUL be provided, through which in the guide rail incident chips or other particles can be ejected, for. B. by a with the roller assembly with moving brush assembly, sweeping lip or similar. Corresponding failure openings can also be used in arrangements with vertical and horizontal support surfaces and treads in the lower guide area in the rear and / or front angle of the U-shape of the guide rail be provided.

The above and those specified in the claims as well as the figures removable features are both individually as well as in various combinations advantageously feasible. The invention is not limited to the described embodiments limited, but in the context of expert Can s changeable in many ways. The role guidance is not only in the Application for the sliding door a machine panel, but otherwise advantageous used.
